Baby: Mommy, who is the new polar bear cub?
Mom: His chromatography left him, so he is now in our mixture. Now we are a different compound of different elements.
Baby: What's a chromatography mommy?
Mom: A seperation of mixtures. It's passing a mixture through a stationary phase to be measured.
Baby: Ooohhhhh! That's soooo coool! I want to be a chromatography!
Mom: OH NO YOU DON'T!
This is a rhyme we made to remember the difference between an element and a mixture:
Elements give us excitment because they cannot be seperated.
Compounds make us happy cause it is a pure substance made from two or more elements.
Mixtures give us smiles because it’s a combination of two or more.
Observations of a Solution:
Yellow in color.
Transparent.
Liquid.
Odorless.
Solution: A mixture that appears to be a single substance (homogenous) but is composed of 2 or more substances that are distribute evenly amongst each other.

Today we are finding out what Fractional Distillation and Oil refineries are and things about them. Oil refineries take crude oil and turn it into products like gasoline, jet fuel, crayons and plastics. View this link

Will the mass change when a tablet is added?
The second test with three pieces changed because the cap was not put quick enough.
The two other tests followed the law of conservation of mass.
